Importing a PDF into another PDF as a layer 1. Open the Layers Navigation panel (View > Navigation Panels > Layers). 2. In the Layers panel, click on the Options menu pull-down ( ), and choose Import as Layer. Name the layer, and choose options for position, scale, opacity - even position the layer behind the existing contents. Importing a PDF as a Layer Select another PDF to import as a layer, and choose scaling, stacking order, position, and opacity options. Using Other Applications to Edit PDF files Using the TouchUp tools is the recommended method for editing content in a PDF. Still, be cautious about accidentally modifying content, and carefully examine edited PDFs to ensure that no unintended changes have occurred. Adobe does not recommend that you attempt to edit PDFs outside of Acrobat, however. For example, while Illustrator will open a PDF, it is intended to open only PDFs that were created by Illustrator. PDFs created by other applications-even Adobe InDesign-are not intended to be edited in Illustrator. Font embedding may be damaged, content may become corrupted, and there is no guarantee that such edits won't greatly impair file integrity. It's still best to return to the originating application, perform the necessary edits there, and generate a new, corrected PDF. Convert Colors Using the Convert Colors feature, you can convert color objects in a PDF document to CMYK or another color space. Acrobat uses the source color spaces of objects in the document to determine what (if any) color conversion is required. Acrobat manages the colors using embedded profiles (if they exist) or default or user-defined color spaces. You can convert the colors of a single page, a range of pages, or an entire document. Note: To convert only the color of a selected object, use the TouchUp Object tool. The Convert Colors function in Acrobat 9 Pro includes a revamped interface, access to the Ink Manager (and the ability to permanently process Ink Manager changes), as well as several new options: • Preserve Black: If R, G, and B values are the same, this options will convert to an equivalent percentage of process black. This is especially useful for handling PDFs from Office files intended for high-end printing, to avoid multi-color output of text and other elements intended to print as black. • Promote Gray To CMYK Black: Converts device gray to CMYK, not to rich black.
